First, the pathogen of rabbit lice: The pathogen that causes rabbit lice in rabbits is generally Haemophilus rabbits , The adult rabbit bloodthirsty louse is 1.2 to 1.5 mm long, and it mainly depends on sucking the blood of the rabbit to maintain its life. An adult louse can suck blood about 0.2 to 0.6 mm a day. After the mature female parasites parasitize the rabbit, it will release a cylindrical egg with a sticky substance, and attach to the root of the rabbit’s hair. The larvae undergo 3 molts in 2 to 3 weeks before developing into sexually mature adults.
II. Epidemiology: Rabbit pediculosis is mainly contagious. Healthy rabbits become infected after contact with rabbits with rabbit lice. In addition, they may also become infected through contact with rabbit cages and utensils contaminated by infected rabbits.
Clinical symptoms of rabbit lice: Rabbit lice secrete a poisonous saliva when sucking blood, which stimulates the rabbit’s nerve endings and causes Intense itching, resulting in restlessness, loss of appetite and poor rest in the rabbit. Sometimes small nodules or small bleeding spots appear on the skin of affected rabbits. Suffering rabbits will also frequently chew or rub the skin around because of itchy skin, resulting in skin damage. In this case, the rabbits may have secondary bacterial infection, causing purulent dermatitis. In addition, rabbits will gradually lose weight after suffering from rabbit lice, and young rabbits suffering from this disease will show stunted growth. Therefore, rabbit lice disease is extremely harmful to young rabbits, and it will also greatly reduce the quality of rabbit hair.
Fourth, the diagnosis method of rabbit pediculosis: Pull out the rabbit’s coat
by hand, It can be seen with the naked eye that there are small black rabbit lice moving on the skin surface of the rabbit, and yellowish eggs can be seen on the roots of the rabbit’s hair.
Differential Diagnosis:
The symptoms of rabbit pediculosis and mite disease are very similar, many people will confuse these two diseases, and breeders should pay attention to distinguish them. Rabbit lice and mites are both contagious and cause symptoms such as itching, biting, and rubbing in rabbits. However, these two pathogens are different, the pathogen of mite disease is mites or itch mite. The mites mostly live in the external auditory canal of rabbits, and are usually accompanied by symptoms such as crusting and exudate. The scabies mites are mainly parasitic in the epidermis of rabbits and can also cause severe itching in affected rabbits.
V. Prevention and control measures of rabbit pediculosis
1. Preventive measures
First of all, when introducing breeding rabbits, breeders must pay attention to avoid introducing rabbits with pediculosis into healthy rabbit farms; check the rabbit group regularly, and isolate and treat the rabbits immediately if they are found to be infected; Keep the rabbit house clean, dry, and sunny; deworm the rabbit regularly.
2. Treatment method
Ivermectin was used for treatment at a dose of 0.02 mm per kg body weight, and a subcutaneous injection was performed once, and the treatment effect was significant; or 0.0023% flies were used Toxic phosphorus or 0.5% to 1% trichlorfon solution is rubbed on the body surface of the affected rabbit for treatment; or 20% fenvalerate 5000 to 7500 times dilution is rubbed, and the therapeutic effect is remarkable.
